How Does the GRID Task Team Work?

• Task Team – overall coordination, identify issues and key technical areas of interest, initiate and staff tiger teams, coordinate implementation schedules, make general agreements, provide peer pressure to accomplish!

• Network Team – supports network issues; e.g. bandwidth testing, study firewall issues

• Tech Team – get technical expertise to provide tech support, identify technical areas of interest, and implement grid capabilities

• Small focussed tiger teams to explore specific topics and issues

How Does the Grid Team Work?

• Monthly Task Team telecons for everyone• Bi-weekly Tech Team telecons for tech team• Frequent as needed telecons for specific tiger

teams to study specific topics/issues.• Multiple email lists• Public Task Team website at

http://harp.gsfc.nasa.gov/grid• Password protected working website at http://grid-tech.ceos.org/gridwiki

Issues

• CEOS Grid issues: – Six application projects with widely differing application areas.– Many issues are common to all six projects.  – Project team is working together to gain insight into these common

problems.• Issue 1: Lack of Grid software how-to install and use documents:

– Team is producing how-to documentation: Grid Cookbook pages.– 1st cookbook page: How to install and configure Globus 2.2.– 2nd cookbook page: How to install and configure GridFTP with multiple

hosts and multiple clients.– 3rd cookbook page (in progress): How to put simple applications on the

Grid – e.g. Web Map Server Application on the GRID• Issue 2: Lack of Grid expertise by participants:

– Grid Experts (IPG, . . .) are acting as consultants on various specialty topics.

– Formed Tech Team to help each other and help later participants.

Main Issues, Cont’d.

• Issue 3: Most agencies have firewalls. How to deal with these and how to configure to allow access?

– Network Team is gathering requirements for firewalls and is drafting a "CEOS Grid Firewall Best Practices" document. Jeff Smith will give a talk on this

– Technical POCs interested in this issue will review document with their firewall administrators and will iterate on the document.

• Issue 4: Grid Monitoring:– Network bandwidth performance testing and checkout of network routing is

being performed between testbed nodes. Results of initial network bandwidth testing by Andy Germain is accessible online

– Several Grid Monitoring tools (Map Center, Ganglia, NWS) are being studied and tried out.

– Map Center monitoring tool can monitor host machine ports and perform process level monitoring.

– CEOS Grid application sites are linking to this tool to try it out (work in progress).

Main Issues, Cont’d.• Issue 5: Certificate Authority (CA): How should host and user certificates be

implemented in an international multi-agency consortium?– Small tiger team formed to study issue with Grid expert.– Procedure for CA has been drafted and is being reviewed.– IPG Certificate software being tested– Planning to use certificates from multiple sources (work in progress).– Allan Doyle will give talk on this

• Issue 6: Catalog Issues: Because EO data have huge volumes from many sources, need a product catalog that is searchable and scalable. What kinds of catalog components are available on the Grid and do these components have the necessary capabilities for CEOS catalogs?

– Grid experts on SDSC SRB/MCAT and Globus MCS invited to give presentations to entire team.

– Catalog Tiger team formed (small team to study and analyze catalog issues and report back to the main team - work in progress). Liping Di will give Grid Catalog report at the ICS meeting on Wednesday

• Issue 7: Putting EO applications on the Grid:– Small tiger team formed to study this issue and prototype at least one approach.– Prototyping OGC Web Map Server (WMS) and Web Coverage Server (WCS) on the Grid.– Will generate Cookbook pages on putting WMS and WCS on the Grid.

Grid Network Team

• Led by Jeff Smith• "Virtual" CEOS Grid Prototyping Network is actually made up of

connectivity from several High Performance Research and Education Networks (HPRENs), e.g., NASA Research and Education Network (NREN), Energy Science Network (ESnet), Internet2 Abilene, European HPRENs.

• Network team works to ensure adequate connectivity between testbed nodes:– Identify connectivity requirements (testbed network map).– Perform network performance testing.– Work to solve specific network connectivity problems as needed.

• Developed CEOS Grid Firewall Best Common Practices (BCP) Document:– Working with USGS to implement, test and refine document.– Will work with other organizations to test and refine document further
